Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87378, here are decompositions:
- 19 + 87359 = 87378
- 41 + 87337 = 87378
- 61 + 87317 = 87378
- 79 + 87299 = 87378
- 97 + 87281 = 87378
- 101 + 87277 = 87378
- 127 + 87251 = 87378
- 157 + 87221 = 87378
Showing the first eight; more decompositions exist.
